Decrease in osteoarticular tuberculosis in Spain between 1997 and 2018

Background and objective osteoarticular tuberculosis represents 2%-5% of the manifestations of tuberculosis. The objective was to calculate the incidence and describe the epidemiological characteristics of patients with osteoarticular tuberculosis who received hospital care in Spain between 1997-2018. Methods A retrospective study was conducted of patients treated with osteoarticular tuberculosis in Spanish hospitals between 1997 and 2018, using the data from the Minimum Basic Data Set at hospital discharge, using the ICD-9-CM and ICD-10 codes. Results 5710 patients with osteoarticular tuberculosis were detected over the 22 years in Spain. The mean annual incidence for the period was 6 cases per million inhabitants (95% CI 5.58-6.30). There was a significant difference between the mean annual incidence per million inhabitants of the first period (1997-2007) of 6.95 and that of the second (2008-2018) of 5.35 (p Conclusions The incidence of osteoarticular tuberculosis in Spain is low, has reduced over 22 years and predominates in men.
